Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite material for reinforced concrete beams,

The present invention relates to a steel composite beam using a supporting reinforcement frame and a method of constructing a structure using the same. More specifically, the present invention relates to a steel composite beam using a support reinforcement frame that can more effectively secure a section rigidity when a steel composite beam including a steel beam and a lower casing concrete is installed in a column structure, and a method of constructing a structure using the same .

FIG. 1A is a sectional view showing an example of installing a composite plate 20 on a pillar structure and installing a bottom plate using the deck plate 10. FIG.

The composite beam 20 is a beam synthesized from an I-shaped steel material and concrete used in a building structure. The lower concrete 25 is formed at a lower portion of the I-shaped steel material 23, And a central concave portion having an open upper portion.

It can be seen that the lower flange of the I-shaped steel material 23 is embedded in the bottom surface of the central groove portion.

The lower concrete 25 is provided with a lower reinforcing bar 24 extending in the longitudinal direction and an upper portion of which is covered with the lower reinforcing bar 24 so as to protrude upward from the upper surface of the lower concrete 25, It is understood that the reinforcing bars 22 of the reinforcing bars are disposed.

At this time, it can be seen that the upper reinforcing bar (21, compression reinforcing bar) of the composite beam is arranged in the same direction as the lower reinforcing bar (22) through the upper end of the reinforcing bar (22)

In this case, a column structure (not shown) constituting a frame of the building structure is installed first, and a composite bar 20 on which the upper reinforcing bar 21 is disposed is connected to the column structure.

When the final column structure and the composite beam 20 are installed as described above, a deck plate 10 for installing the bottom plate 40 is installed between the beams.

That is, it can be seen that the deck plate 10 is installed so that the bottom plate 11 of the deck plate 10 is placed on the side upper end of the lower concrete 25 of the composite beam 20.

After the deck plate 10 is installed, it can be seen that the bottom plate concrete is installed on the top of the deck plate 10 to form the bottom plate 40 (slab), thereby completing the formation of the final column structure, beam and bottom plate.

However, as the cross section of the lower concrete 25 becomes larger, the weight of the composite beam 20 must be increased. Therefore, the conventional composite beam 20 can not be used as a composite beam between the long sides.

FIG. 1B is a perspective view showing another example of the composite beam 30 used in constructing the bottom plate using the deck plate and the composite beam on the column structure.

The composite beam 30 is used as a connecting means with the columnar structure by using an asymmetric I-shaped steel beam 31 formed at its both ends with an upper flange having an extended length L1, A vertical side plate 50 is provided on both side upper surfaces of the lower flange 32 so that the bottom plate concrete 34 can be poured into the inner space S between the supporting stiffeners 50, 30 are integrated with each other by the Leticus root 40.

At this time, in the inner space S, a tensile member 40 is disposed in the longitudinal direction of the composite beam 30 to introduce a prestress into the filled concrete, and the reinforcing roots 40 and the inner reinforcing bars are reinforced.

However, since the vertical side plate 50 is provided on the upper flange of the asymmetric I-shaped steel beam 31, the width and the length of the lower flange of the asymmetric I-shaped steel beam 31 must be secured to a certain degree There is a possibility that the asymmetric I-shaped steel beam 31 may be restricted and the economical efficiency may deteriorate.

Accordingly, the present invention provides a support reinforcement frame which is formed so as to be able to construct a bottom plate by a deck plate or a precast slab (unidirectional precast slab) by making a steel composite beam more economically and installing it on a column structure And a method of constructing a structure using the same.

According to an aspect of the present invention,

First, an I-shaped steel beam formed of an I-shaped section including an upper flange, an abdomen, and a lower flange is used as the steel composite, and a lower casing concrete is formed to surround the lower flange and the lower abdomen, Inside the lower casing concrete, there is used a material in which a tensile force is introduced by using a tension material extending in the longitudinal direction.

At this time, the end of the I-shaped steel beam is formed to protrude from the both end faces of the lower casing concrete for connection with the pillar structure.

Further, the lower flange of the I-shaped steel beam is formed to be smaller than the width of the upper flange so that the tension member and the inner reinforcement can be easily installed in the lower casing concrete.

At this time, the I-shaped steel beam has a larger width than the width between the upper and lower flanges at both ends protruded from the lower casing concrete, thereby facilitating connection with the column structure and reducing the amount of steel used.

Second, a support reinforcing frame (a channel member and a side plate are assembled in the form of a rectangular frame) is fixedly installed on both side surfaces of the lower casing concrete to form an internal space S between the abdomen portions of the I-shaped steel beam. S) to fill the bottom plate concrete. The support reinforcement frame is used as a support for supporting the deck plate or the precast slab on the upper surface.

At this time, an upper end reinforcing member such as a-shaped steel is used on the upper surface of the support reinforcement frame to prevent breakage or positional change due to the support of the deck plate or the precast slab.

In addition, the supporting reinforcement frame is formed in a rectangular shape so that the deck plate or the precast slab does not have a problem of deformation due to its own weight, and unnecessary reinforcing bars or the like need not be separately installed in the inner space, .

Third, the supporting reinforcement frame is formed to be formed in an inverted U-shaped squared box, but spaced apart in the longitudinal direction of the lower casing concrete. Such a support reinforcement frame can be limitedly installed at both ends of the steel composite beam as necessary, and can be effectively accommodated by the bracing member constituting the support reinforcement frame.

Since the present invention uses a steel composite beam including an I-shaped steel beam and a lower casing concrete into which a tensile force is introduced, it is possible to reduce the height of the cross section between the long and narrow beams. .

In addition, since the steel composite is manufactured by forming the lower casing concrete at the lower part of the I-shaped steel beam, it is possible to minimize the amount of steel used and to freely select the size of the lower casing concrete section. It is easy and economical enough to be secured. This makes it possible to construct a more economical building structure or the like by using the steel composite sheet of the present invention.

Furthermore, it is possible to stably install the support reinforcement frame while controlling the tensile stress generated on the upper casing concrete by installing the support reinforcement frame on the lower casing concrete of the steel composite beam, thereby providing the steel composite box with durability and safety .

 [Steel Composite Beam (100) according to the Present Invention]

[Example 1]

The steel composite beam 100 according to the first embodiment of the present invention is a composite beam of the steel beam 110 and the lower casing concrete 120 and will be described with reference to FIGS. 2A and 2B.

First, the steel beam 100 uses, for example, an I-shaped steel beam as a beam extended so as to have an entire length L of the steel composite beam 100.

The I-shaped steel beam is formed by including an upper flange 111, a waist portion 112 and a lower flange 113 as shown in FIG. 2A. Preferably, the width of the lower flange is smaller than the width of the upper flange Steel beams are used.

At this time, a front end coupling member 114 such as a stud is formed on the upper surface of the upper flange 111 and the bottom surface of the lower flange 113.

Further, as shown in FIG. 2C, both end portions of the I-shaped steel beam are further protruded from the end face of the lower casing concrete 120 for connection with the column structure 200.

The lateral width of the upper flange and the lower flange at both ends of the I-shaped steel beam is greater than the width between the ends of the I-shaped steel beam for connection with the connector 210 installed in the pillar structure 200.

Accordingly, the I-beam 110 can reduce the amount of steel used to make it economical, and the amount of steel used is small to make the section smaller. However, the I-beam 110 is supplemented by the tension introduced into the lower casing concrete 120.

Such I-shaped steel beam 110 is a built-up I-shaped steel beam which is separately manufactured using a steel plate.

The steel composite beam 100 of the present invention forms the lower casing concrete 120 as shown in FIGS. 2B and 2C, instead of minimizing the cross section of the I-shaped steel beam.

That is, the lower casing concrete 120 has a rectangular cross section formed to surround the lower flange and the lower portion of the abdomen of the I-shaped steel beam, and the tensile member 130 and the inner reinforcing bar 140 are disposed therein. As shown in FIG.

That is, the tensile stress is generated by the action load of the lower portion of the neutral axis of the I-shaped steel beam 110. The tensile stress is such that the lower flange and the abdomen are burdened by the steel, and the lower casing concrete 120 is formed So as to surround the lower portion of the I-shaped steel beam.

However, since the lower casing concrete 120 is formed of concrete, it is prone to tensile stress by introducing compressive tensile force by using the tensile material 130 because of its large weight and weak tensile stress.

In addition, by combining the I-shaped steel material and the lower casing concrete 120 into which the tensile force is introduced, it is possible to install the steel composite material 100 in an easy and more long interval that minimizes the sectional height, .

As shown in FIGS. 2A and 2B, the lower casing concrete 120 is reinforced using the inner reinforcing bars 140. The inner reinforcing bars are divided into horizontal reinforcing bars 141 and strip reinforcing bars 142 extending in the longitudinal direction. .

The horizontal reinforcing bars 141 and the reinforcing bars 142 are arranged so as to be wrapped around the lower flanges of the I-shaped steel beams in advance.

As shown in FIGS. 2A and 2B, the steel composite beam 100 of the present invention is formed such that a lower casing concrete 120 is formed under the I-shaped steel beam 110, 150 are formed.

The supporting reinforcement frame 150 is formed to include the upper reinforcing member 153, the pillar member 154, the upper connecting member 155, the bracing member 156 and the side plate 157.

First, the pillar member 154 is spaced longitudinally from the upper surfaces of the left and right side ends of the lower casing concrete 120 using, for example, a b-channel member. Therefore, since the load transmitted from the deck plate or the precast slab (unidirectional precast slab 400) is effectively supported on the lower casing concrete 120, it is possible to reduce the installation amount of the channel member, .

At this time, in order to reinforce the damage of the column member due to the support of the deck plate or the precast slab (unidirectional precast slab 400) on the upper surface, the upper reinforcement member 153 is continuously extended in the longitudinal direction As shown in FIG. The upper end reinforcing member 153 eventually binds the pillars 154 together.

The upper connecting member 155 is connected to both sides of the abdomen 112 of the I-beam 150 of the I-shaped steel beam 100 and also uses a b-channel member, for example.

The bracing member 156 connects the end of the upper connecting member 155 and the lower end of the pillar member 154 so that the upper reinforcing member 153, the pillar member 154, and the upper connecting member 155 are constrained So that stable self-standing installation is possible.

Also, the bracing member 156 may serve as a synthetic joint member or a shear connection member for enhancing the composite performance with the bottom plate concrete 300 placed in the internal space S.

The bracing member 156 may also be a b channel member or a bolt-like fastener. Accordingly, the upper reinforcement member 153, the pillar member 154, the upper connecting member 155, and the bracing member 156 of the present invention may be assembled together by welding or fastening.

Further, a base plate (not shown) may be provided for supporting the bottom of the pillar member 154 while allowing the pillar member 154 to be installed more stably. The base plate serves to restrain the lower ends of the pillar member 154 from each other I can expect.

Accordingly, the support reinforcement frame 150 is formed in an inverted U-shape as a whole, and is formed on the entire upper surface of the lower casing concrete 120 over the entire length of the extension portion or on a part thereof.

At this time, it is preferable that the tensile force by the tensile material 130 is introduced into the lower casing concrete before the support reinforcement frame 150 is installed and a pair of the support reinforcement frames 150 are provided on both upper and lower sides of the lower casing concrete 120 .

This is because, when the support reinforcement frame 150 is installed first, the tension is introduced into the support reinforcement frame 150, so that the efficiency may be lowered in introducing a required tension force into the lower casing concrete.

Further, when the supporting reinforcement frame 150 is fixed to the lower casing concrete 120, the installation amount of the vertical side plate 50 can be remarkably reduced compared to FIG. 1B, which is more economical.

The side plate 157 is installed in the form of a vertical plate on the side of the pillar member 154 by means of fasteners so as to serve as a form of a bottom plate concrete 300 to be described later, So that it can be reused.

Further, it can be seen that an internal space S is formed between the supporting reinforcement frame 150 and FIG. 2C, and the bottom plate concrete 300 is installed in the internal space to be filled.

The steel composite sheet 100 according to the present invention is formed by the side plate 157 of the supporting reinforcement frame 150 that serves as a concrete to be formed with a width equal to the width of the lower casing concrete 120 in the transverse direction, .

In addition, the tension member 130 is fixed to the end surface of the lower casing concrete 120 after being strained. In order to serve as a support plate, the tension member 130 is inserted through the end surface of the lower casing concrete 120 as shown in FIGS. A fusing plate 121 having through-holes as shown in FIG. 2B is formed.

Referring to FIG. 2d, in the case of the support reinforcement frame 150 of the present invention, when the height of the support member 150 is small and the height of the column member 154 is small, the bracing member 156 may not be installed separately. .

FIG. 2B is a partially exploded perspective view illustrating a means for solving the problems of deformation or breakage of the position of the concrete reinforcement frame 150 according to the present invention.

The support reinforcement frame 150 functions basically as a form of a deck plate or precast slab 400 and a supporting means for supporting the deck plate or precast slab on the upper surface.

2b shows that the bracing member 156 of the support reinforcement frame 150 is installed using the upper connecting member 155 using the connecting plate 158 (in the form of a polygonal plate) So as to be connected to both side surfaces of the abdomen portion 112 of the I-shaped steel beam 100 so as to have a reinforcing function by load transmission and breakage.

Further, between the upper surface of the upper flange 111 of the I-shaped steel beam 100 and the upper surface of the upper end reinforcing member 153

The support reinforcement frame 150 can be more stably set by providing the support reinforcement frame connector 151 such as a bending band.

[Example 2]

The second embodiment shows that the support reinforcement frame 150 can be formed only at both end portions of the steel composite 100, rather than the entire length of the steel composite 100, as compared to the first embodiment.

2E, the support reinforcement frame 150 includes a support reinforcement frame 150, which includes an upper reinforcement member 153, a pillar member 154, an upper end connection member 155, a bracing member 156, and a side plate 157 The steel composite beam 100 may be formed so as to be formed at a position spaced apart from both end surfaces of the steel composite beam 100 toward the central portion and may be formed so as to be closer to the abdomen of the steel beam 110 It is possible to install the bottom plate concrete 300 in the limited internal space S by using a stagger plate or the like.

[Steel Composite Beam 100 and Deck Plate or Precast Slab (400) of the Present Invention]

3A and 3B are a perspective view and a cross-sectional view, respectively, of a deck plate or a precast slab 400 in a state where the steel composite member 100 of the present invention is installed between the columnar structures 200.

First, it can be seen that the pillar structure 200 is constructed in the form of a vertical beam, but it can be formed with various cross-sections and materials such as a pipe member. Thus, FIG. 3A shows that four pillar structures 200 are being constructed .

Both ends of the steel composite beam 100 are connected to the four column structures 200.

It is noted that the steel composite beam 100 includes the I-shaped steel beam 110, the tensile force introduced therein, the lower casing concrete 120, and the support reinforcement frame 150, have.

It can be seen that both end portions of the steel composite beam 100 are exposed to the I-shaped steel beam 110 as they are and are connected to the coupling 210 of the pillar structure 200.

It can be seen that a deck plate or a precast slab 400 is installed between the steel composite beams 100. The bottom plate 410 of the deck plate or the bottom surface of the precast slab is fixed to the upper surface As shown in FIG.

As a result, the load transmitted to the deck plate or the precast slab 400 is transferred to the support reinforcement frame 150, and the load is distributed to the steel composite box 100.

Further, when the deck plate or the pre-cast slab 400 is installed to be supported by the support reinforcement frame 150, it may be affected by the operation load at the time of installing the bottom plate concrete. As shown in FIG. 2B, the supporting reinforcement frame 150 may be connected to the support reinforcement frame 151, such as a bending band, so that a stable setting can be performed.

Both end portions of the support reinforcement frame connection member 151 may be fixed to the upper surface of the support reinforcement frame 150 and may be bent or bent through the upper surface of the upper flange of the I-shaped steel beam 110, Horizontal reinforcing bars may be used, and they are embedded in the steel composite by the bottom plate concrete, thereby acting as reinforcing bars and reinforcing bars.

3A and 3B are not drawn on the basis of FIG. 2E, but it goes without saying that the support reinforcement frame 150 according to FIG. 2E can also be used.

[Method of constructing structure using steel composite beam using support reinforcing frame of the present invention]

4A, 4B and 4C are construction and cross-sectional views of the steel composite member 100, the pillar structure 200 and the deck plate or precast slab 400 of the present invention.

As shown in FIG. 4A, the column structure 200 may have various shapes, but the present invention will be described with reference to the case of the I-shaped steel beam.

The columnar structure 200, which is an I-shaped steel beam, is formed with a connecting hole 210 for horizontally projecting the steel composite member 100 of the present invention.

These connectors can use H-beams like I-beam steel beams.

The steel composite beam 100 as described above is set between the columnar structures 200 and the I-shaped steel beams 110 protruded at both ends are fastened to each other using bolts, nuts, do.

It can be seen that the steel composite structure is composed of the I-shaped steel beam 110, the tensile material 130 and the inner reinforcing bars 140 and the lower casing concrete 120 into which the tensile force is introduced and the supporting reinforcement frame 150 .

Next, as shown in FIG. 4B, a deck plate or a precast slab 400 is installed between the adjacent composite beams. The deck plate or the precast slab 400 is installed such that the ends of the deck plate or the precast slab 400 span the upper surface of the support reinforcement frame 150 .

Thus, it can be seen that the steel composite sheet 100 is used as a support means for the deck plate or precast slab 400.

Next, as shown in FIG. 4C, a plurality of steel composite beams 100 are installed between the pillar structures 200 and a deck plate or precast slab 400 is installed. And the bottom plate concrete 300 is poured from the upper part.

Thus, the bottom plate concrete 300 is formed to have a constant thickness from the composite beam surface to form a bottom plate.

As a result, it can be seen that the bottom plate is completed in the column structure 200 by using the steel composite sheet 100, the deck plate or the precast slab 400 of the present invention.
